I have taken your advice to change my oil every 3000 miles. In order to establish a better relationship with my vehicle and save money, I've decided to do the work myself. Now, what do I do with the used oil?

TOM: Don't pour it down the sewer and don't put it into a Hefty bag...no matter how tough that fat guy on TV says they are. Motor oil is a hazardous waste and should not be disposed of along with your regular household trash. Most places that sell you new oil will take back the same amount of used oil in sealed containers with proof of purchase.

This is even law in some states--including Massachusetts where you live. Elsewhere, the state department of environmental protection will be happy to tell you where you can safely dispose of used motor oil. If that's too much trouble, you can always do what my brother does and use it on your hair.

RAY: Right, it doesn't make anything grow, but it darkens my scalp, and from a distance, it almost looks like thick locks.
